How to Add Power Management to an OS Design (Windows CE 5.0)
You can add support for power management to an operating system (OS) image to reduce power consumption on a target device and preserve the file system in RAM during the reset, on, idle and suspend power states. By adding power management to your OS design, you can also improve overall OS power efficiency and enable the OS to coexist with applications and drivers that do not support power management.
To track your progress in the following table, select the check box next to each step.
| Step | Topic | |
|---|---|---|
| 1. Create an OS design for a specific board support package (BSP). | Creating an OS Design | |
| 2. Add the Power Management (Full) or Power Management (Minimal) catalog item to your OS design from the Platform Builder Catalog.
The Power Management (Minimal) Catalog item implements all of the required power management application programming interfaces (APIs). These APIs are not fully functional. The Power Management (Full) Catalog item fully implements the entire power management framework. All APIs and features are fully functional. For more information on Power Management functionality, see Core OS Services. |

| 3. Add power management support to a custom device driver.
This step is optional. If you do not have a custom driver you want Power Manager to manage, proceed to the next step. |

| 4. Build your run-time image.
If your run-time image builds correctly with no errors, you have successfully added power management to your run-time image. |
